turkeygirl2,
For that amount of money, I would go with either a Moultrie M-40, Moultrie I-40, or a Scoutgaurd. I don't think you will be disapointed with any of those choices. As for a security box, depending on the amount you want to spend, check out
www.swivelsafe.com These dudes are heavy and pretty much theft-proof, short of cutting down the tree it's in. They are pricey, about $100.00, but they are worth it. You can also find security boxes at
www.camlockbox.com they are cheaper in price but I don't have any experience with them. They do look well made though. Whatever you decide, the addicts here will be looking forward to your pics.
Blessings.....Pastorjim
